Answer:
The range is 40.
Step-by-step explanation:
Range is just the largest number minus the smallest.
70 - 30 = 40
Answer:
Point-Slope: 
Slope-Intercept: 
Step-by-step explanation:
The point-slope formula is 
. The slope-intercept formula is 
. Since we are given the point and slope, we can directly plug it into the point-slope formula.
Point-Slope
To find the slope-intercept form, we can manipulate the point-slope form to get the slope-intercept form.
Slope-Intercept
Answer:
the graph of the function f(x) = −3x2 − 3x + 6 is shown. Which statements describe the graph? Select three options.
On a coordinate plane, a parabola opens down. It goes through (negative 2, 0), has a vertex at (negative 0.5, 6.75), and goes through (1, 0).
The vertex is the maximum value.
The axis of symmetry is x = negative one-half.
The domain is all real numbers.
The range is all real numbers.
The function is decreasing from (−∞, 6.75).
Step-by-step explanation:
3.03 days
Step-by-step explanation:
We first look up the Z-score for 90th percentile in the table;
= 1.282
Z score is given by the formula;
X – μ / σ
We are given μ as 5.2 while σ is 2.2. Therefore;
1.282 = X - 5.2 / 2.2
1.282 * 2.2 / 5.2 = X
3.03018 = X
= 3.03
